BOHR'S MODEL OF THE ATOM

Old Model of the Atom:
-Like planets moving around the sun
-Emits radiation when moving (form of light)
-Problem: Why don't the electrons spiral into nucleus??

Bohr's Model: Solved Problem^^

Energy= (Planks Constant) x (Frequency) **Frenquency determines energy

E=hf

h= 6.626×10-34

In an atom;
-Specific energy levels (n) are present
examples: n=1, 2, 3 etc
-The larger the energy level, the more energy the specific electron has
-When the energy in an electron decreases to a specific level, the electron will "leap" to that energy level

Excited State
-Creates an electron transition

Makes quantum Leaps
-To different energy levels (not going in betweeen)
-Electrons exsist in whole number wavelengths
